WIRE-CHAIN Linn.

Application filed May 31,

To all whom it may concern:

Be it known that MAURITZ OLSON, a citizen of the United States, and"resident of Bridgeport, inthe county of Fairfield and State ofConnecticut, has invented certain new and useful Improvements in Wire-Chain Links, of which the followingis a specification.

This invention relates to-wire chain, the

links of which are alike in construction and each made of a single pieceof wire bent to form a loop and a transversely arranged eye throughwhich the loop. of the adjoining link is joined during the automaticmanufacturing and assembling of the chain.

The object of my invention is to improve upon that style of Wire chainknown as Triumph chain, which is similar in some respects to theconstruction of chain link shown in Patent #564,406 and particularly toproduce a link the side members of the loop of which are substantiallyparallel with each other and the shoulders of which formed at theintersection of the eye andloop are arranged at an intersecting angle.A. further and essentialfeature of the invention is to provide a link,the endportions of-the wire of which are bent in around the shoulders ofand in aligmnent with the wire of the eyes and against the peripheral orback portion of the eye' in a way to cover the two wire ends, and toform a finished and smooth running link. 1

The invention further resides and consists in the construction and novelform of link hereinafter to be more fully described, illustrated in theaccompanying drawing and pointed out in the claims hereto appended.

Similar characters of reference denote like or corresponding partsthrough the several figures of the accompanying drawings forming part ofthis specification and upon which I Fig. 1 showsa top plan View of apieceof wire chain, the several links of which are constructed inaccordance with the features of my invention;

Fig. 2 is an edge view of the chain shown in Fig. 1; and

Fig. 3 shows a bottom chain seen in Fig. 1.

All of the links shown in the drawing are alike in construction and eachis formed from a single piece of wire of proper length, bent atits'center to form a loop,.the end plan View of the .struction; andcomprises formed end portions of the wire, positioned 1922. Serial No.564,709.

I portions being shouldered and brought togethen and curled to form aclosed eye through which the end portion ofthe loop of the adjoininglink is hingedly connected.

In the drawing, A representsthe loopportion of the link and B the eyeportion. The loop comprises an outer rounded end 1301' pair of inwardlydisposed shoulders "c"c formed at the intersectionof the loop and Theseshoulder portions are formed by inon a, two parallel side members Z) b,

eye," sometimes designated "as the shank.

wardly deflected portions of the side mem-' bers, arranged in the sameplane as that of the two sidemembers ?)b though atinter secting angles,Theeye is of double contwo similarly side by side and so shaped and tiedthat thelr openings align one with the other, better to accommodate theloop portion of the adjoining link. i r

The side members are bent in at intersecting angles to form theshoulders cc and are then bent around at an acute angle .to formthe twoeye portions d-d. The eyes are substantially round in shape and aresecured by the ends beingtied to the shoulders. The end portions ec ofthe wire are passedover. the outer side of the two shoulders and bent intoward each other and then disposed forward lengthwise of the link andalong side of each other with their ends f7 positioned against theperiphery of the link in a wayto cover the said ends and to form a linkwith no rough projectingwireends, thereby forming a chain that is smoothto handle and which will run through the hand without injuring the same.i j

F rom" the foregoing itwill be seen that the two end portions 6-6 aredisposed towardand in alignment with the plane of the bends of the wireforming the two eye memhers and that the two ends proper are positionedagainst the outside of forming said eyes.

3 Having thus described what I claim and ters Patent is, k

1. Awire chain link made from a single piece of wire and bent to form,and comprising a loop portion and a double eye portion, shoulders formedat the intersection of loop and eye and at intersecting angles myinvention,

desire to secure by Letthe wires" with respect to each other, the doubleeye Q of the link comprising two like eyes positioned against each otherand bentaround to'allgn wlth each other the end portions of theWirebeingturned inward throughthefloop and positioned side by sideagainst each other the ends proper being disposed against the peripheryof the respective eyes sin a Way to cover said ends and. form; a

smooth running link.

2. A wire chain llnk madefroni a vsingle piece of Wire and bent to form,andvoonr prising a loop portion and a double eye; portion the said loop'portlon ineludlng rounded outer end and parallelsidememhers,and'shoulders formed intermediate the opposite side members and-- atintersecting eye. of the link beingadjacent to-t'he'fshoul ders andcomprising two like portions of the Wire positioned against eachotherand bent around together to form aligned eyes, said end portions or theWire being positioned against the outside of the respective shoulders ofthe loop and'bent around said shoulders and through said loop andfurther" positioned side by side against each other and int-parallelplanes and having their ends proper disposed against the outerperipheries of the eye in a ay to cover; said ends and form a smoothrunning link.
